Like all learned men, the doctor was absent by nature, and that with the best intentions in the world.

During the first moments, according to the custom of his brethren, he puzzled his brain to endeavour to make out the signification of the words, somewhat cabalistical in his opinion, that he was to repeat to the trapper.

He could not comprehend what assistance his friends could possibly obtain from a half-wild man, who lived alone in the prairie, and whose existence was passed in hunting and trapping.

If he had accepted this mission so promptly, the profound friendship he professed for the niece of the general was the sole cause: although he expected no advantageous result from it, as we have said, he had set out resolutely, convinced that the certainty of his departure would calm the uneasiness of the young lady. In short, he had rather meant to satisfy the caprice of a patient, than undertake a serious affair.

In the persuasion, therefore, that the mission with which he was charged was a useless one, instead of going full speed, as he ought to have done, to the toldo of Black Elk, he dismounted, passed his arm through his bridle, and began to look for simples, an occupation which, ere long, so completely absorbed him, that he entirely forgot the instructions of Doña Luz, and the reason why he had left the camp.

In the meanwhile, time passed slowly because anxiously; half the day was gone, and the doctor, who ought long before to have returned, did not appear.

The uneasiness became great in the camp, where the general and the captain had organized everything for a vigorous defence in case of attack.

But nothing appeared.

The greatest calm continued to prevail in the environs; the Mexicans were not far from thinking it a false alarm.

Doña Luz alone felt her inquietude increase every instant; with her eyes fixed upon the plain, she looked in vain in the direction her expected messengers should arrive by.
